JAMES PIKE AND WILLARD FISK, OF CUMBERLAND, RHODE ISLAND.

PUMP.

Specification of Letters Patent No. 1,285, dated August 13, 1839.

To all whom 'it may concern:

Be it known that we, JAMES PIKE and WILLARD FIsK, of Cumberland, in the State of Rhode Island, have invented certain Improvements in the Manner of Constructing the Common Pump for Raising l/Vater from Wells and other Reservoirs; and we do hereby declare that the following is a full and exact description thereof.

Vile ordinarily construct our pump of metal, as being preferable to any other material.

Figure 1 in the accompanying drawing shows the form in which we usually make it, but it may, of course, be Varied in this respect. Fig. 2 is a vertical section through the cylindrical chamber, showing the arrangement of the piston, lower box, and other parts. Fig. 3 is a similar section, in part, exhibiting the piston and lower box in another position. The other figures show certain parts in detail.

In Figs. 2 and 3, and also in the detailed drawings, like parts are designated by the same letters of reference.

rllhe principal improvements which we have made are intended to facilitate the supply of water through the lower valve, and to provide a more convenient way of letting` off the water by opening both the valves than has been hitherto attained, in order to pre vent its becoming frozen in the pump in cold weather.

A, A, is the cylinder within which is contained the piston and its appurtenances. Below the chamber in which the piston works there is an enlarged chamber B, B, within which is contained the lower valve C. This enlarged chamber will admit of the lower valve C, and the opening W in the plate V, which forms its seat being made as large as may be desired, so that it may be as great, or greater than the water way in the upper box.

e, is the piston rod, which toward its lower end, at c', is made smaller than above to receive the upper valve f, which is made tubular, fitting close to but sliding freely upon the part e of the piston rod, its lower side being made perfectly true that it may fit closely on the metallic rim g, of the piston which constitute its seat. The dotted lines on the sliding valve f, designate the tubular opening through it.

` i, is a collar of leather constituting the packing of the pump, and fitted upon the lower part of the rim g. This rim is shown separately at Fig. Li, 71, It, being the collar of leather, and az, the waterway. The same is shown edgewise at Fig. 7. The lower plate of the piston is marked t', and this is represented as secured to the piston rod by the nut c. This lower piston plate is shown separately at Fig. 5, and edgewise Fig. 6.

The lower valve C, slides up and down through a collar I), supported by a standard M, its shank or stem C being fitted into said collar, and the lever, or lifter N, embracing and raising it when necessary.

To the lower side of the upper valve f, (Fig. 8) is attached a rod L, which passes down through the piston plates, and the lower end of which, when the pump brake is raised, and the piston depressed, will be brought into contact with the lever N, which will cause the valve f, to rise. From the lower valve plate z', descends a shank or rod e, which, when the pump brake is raised to its greatest height, that is to say, to a greater height than ever takes place in the ordinary operation of pumping, will be brought into contact with the lever N, and will raise the valve; and both valves being then open the whole of the water conta-ined in the pump will descend into the well, or reservoir.

Having thus fully described the manner in which we construct our pump, and eX- plained the operation thereof, we do hereby declare that we do not claim any of the parts mentioned by us which are common to other pumps; nor do we claim to be the rst to have devised a plan for the prevention of the freezing of water therein by the opening of the valves, but we do claim to have invented a mode of effecting this object which is new, and superior to any of those heretofore adoptedthat is to say,

IVe claiml. The manner in which we have constructed and combined the sliding valve 7, its rod L, and the lower piston plate z', with its shank or rod e, se as to act upon the lever N, and raise the valves C and f, simultaneously, substantially as herein set forth.

2. IVe also claim the forming of the enlarged chamber B, B, for the purpose of containing t-he lower valve C, increasing the waterway, and admitting the apparatus concerned in the raising of the valves, in the manner described.
